RabbiT 4.7 With New Proxy Chain Selector

RabbIt is a Java-based, caching Web proxy that is intended to
speed up surfing over slow links, by stripping away advertising and
background images, and scaling down images to lower quality JPEGs.
If the latter option is selected, then RabbIT does depend upon an
image converter.

In this release, a bug that corrupted some pipelines requests
has been fixed, and a proxy chain selector has been added so it is
possible to direct internal and external requests to different
paths.
